Agree with you on everything. Moving the fingerprint sensor to underneath the screen is unbelievably stupid, even dumber than the Touch Bar. The Pixel leadership favored shipping something that looks cool to a few idiots to (I assume?) drive sales, over shipping something that works well and is ergonomic.
And even the idiots realize 0 seconds into using the new fingerprint sensor that it's a massive downgrade.
I fantasize about Apple releasing a phone with a fingerprint reader on the back just to teach the Pixel folks a lesson and force them to move the reader back to the back.
